TL;DR
Global investments in clean energy reached $2.2 trillion in 2025, almost double the $1.2 trillion in fossil fuels, according to the IEA. However, systemic waste and ongoing subsidies complicate the energy transition.
The International Energy Agency’s 2026 report confirms that global investments in clean energy last year totaled $2.2 trillion, nearly double the $1.2 trillion invested in fossil fuels, signaling a substantial shift in energy funding priorities.
The IEA report highlights that clean energy investments include solar, wind, nuclear, grid-scale batteries, and grid upgrades. Despite the perception that fossil fuel investments are soaring due to government support, data shows clean energy spending is leading globally.
According to the report, this trend has been evident for over a decade, with clean energy consistently attracting more funding even after accounting for subsidies. Experts like Ingmar Rentzhog of We Don’t Have Time emphasize that fossil fuels remain heavily subsidized, making direct comparisons complex but still favoring clean energy investments.
The report also notes that fossil fuels currently supply about 80% of the world’s energy, but nearly two-thirds of this energy is wasted due to inefficiencies in extraction, refining, and transportation. This systemic waste significantly inflates the actual energy demand, complicating the narrative that more clean energy capacity is immediately needed to replace fossil fuels.
Implications of Growing Clean Energy Investment
This surge in clean energy investment indicates a major shift in global financial flows toward sustainable sources, which could accelerate the transition away from fossil fuels. However, the persistence of systemic waste and subsidies for fossil fuels means the transition is more complex than investment figures alone suggest.
Understanding that nearly two-thirds of fossil fuel energy is wasted underscores the importance of improving efficiency and reducing reliance on polluting, underpriced energy sources. The continued support for fossil fuels, despite the investment in clean energy, raises questions about policy priorities and the true pace of transition.

Decades of Fossil Fuel Subsidies and Systemic Waste
The report builds on a decade of data showing that global energy investments increasingly favor clean sources, despite the continued dominance of fossil fuels. Major economies, including the US, still subsidize fossil fuels heavily, often through tax breaks and direct support, which distorts market signals.
Additionally, systemic inefficiencies mean that a significant portion of fossil fuel energy is lost before it reaches consumers, with estimates indicating that only about 37% of primary energy is converted into useful energy. This waste not only inflates the apparent energy demand but also causes substantial environmental and economic costs.
Recent analyses, such as those from RMI, highlight that the energy system’s inefficiency results in over $4.6 trillion annually in wasted energy, much of which is tied to fossil fuel extraction, refining, and transportation.

Unresolved Questions on Transition Speed and Policy Impact
While investment trends favor clean energy, it remains unclear how quickly systemic waste reduction and policy reforms will accelerate the energy transition. The actual pace of replacing fossil fuel infrastructure and overcoming entrenched subsidies is still uncertain.
Further, the impact of ongoing subsidies and market distortions on the real competitiveness of clean energy remains a subject of debate among experts.

Next Steps in Monitoring Energy Investment and Efficiency
Expect continued analysis of global investment flows and policy reforms aimed at reducing fossil fuel subsidies. Monitoring progress in improving energy efficiency and reducing systemic waste will be critical, alongside efforts to accelerate the deployment of clean energy infrastructure.
Further reports from the IEA and other agencies are anticipated to provide updated data on the pace of the energy transition and the effectiveness of policy measures.

Key Questions
Does the increase in clean energy investment mean fossil fuels are declining rapidly?
Not necessarily. While investments in clean energy are rising sharply, fossil fuels still supply about 80% of global energy, and systemic inefficiencies mean the transition will take time.
Are subsidies still favoring fossil fuels despite the investment shift?
Yes. Many governments continue to provide substantial subsidies to fossil fuels, which distort market competitiveness and slow the transition to cleaner sources.
What is the main barrier to faster clean energy adoption?
Systemic waste, infrastructure inertia, and entrenched subsidies for fossil fuels are key barriers. Addressing these requires policy reforms and efficiency improvements.
How reliable are the investment figures given the overlaps in subsidies?
The figures are directional and do not fully account for all indirect subsidies or environmental costs, so they should be interpreted with caution.
What role does energy waste play in the overall transition?
Energy waste significantly inflates the apparent demand for energy and complicates the transition, as reducing waste could substantially lower overall energy needs.
